A solution of 1M potassium t-butoxide was added dropwise (18 mL, 18 mmoles) over a half hour period. Temperature was allowed to rise to 40° C., and the reaction mixture was stirred at this temperature for 5 hours. The reaction mixture was poured into cold 2N HCl, extracted with EtOAc, dried over Na2SO4, and concentrated under vacuum. Compound was recrystallized from CH2Cl2/hexane to afford the title compound as an off-white solid (1.9 g, 4.5 mmoles).
